FAQ about Menstrual Cups

How does the menstrual cup differ from the tampon?

Both are internal menstrual protection. The menstrual cup collects the blood and the tampon absorbs it. The tampon can be used only once whereas the menstrual cup can be used for many years.

The absorbing capacity of the tampon is given in grams and the capacity of the menstrual cup in milliliters. One ml of menstrual blood is comparable with a gram and so the capacity of tampons and menstrual cups is comparable The capacity of the Lunette menstrual cup is 25 ml (model 1) and 30 ml (model 2). The absorbing capacity of a tampon is 6-18 g.

How to know if my flow is heavy or light?

The dividing line between normal and heavy flow is 80 ml during your periods.


Spotting. A drop or two of blood, not even requiring sanitary pad though you may prefer to use one.
Very light bleeding: Needing to change a low-absorbency tampon or pad one or two times per day, though you may prefer to change them more frequently.
Light bleeding: Needing to change a low or regular absorbency tampon or pad two or three times per day, though you may prefer to change more frequently.


Moderate bleeding:
Changing normal absorbency pad or tampon every three to four hours.
Heavy bleeding: Needing to change a high-absorbency tampon or pad every three to four hours, though you may prefer to change more frequently.
Very heavy bleeding or Gushing: Protection hardly works at all. You would need to change the highest absorbency tampon or pad every hour or two.

Can I sleep or swim with the cup?

For sure you can! Cup is really easy when swimming since there are no string attached.

Do I have to remove the menstrual cup when I go to the toilet?

No. You can normally go to the toilet when you’re wearing your Lunette. After a bowel movement, you might want to check that the menstrual cup is still sitting properly. Please do not forget your hand hygiene here!

Can I use the Lunette menstrual cup with an IUD?

Of course. If you do use an IUD, consult with your doctor about cutting the strings as short as possible and monitor their length regularly during periods. If the strings seem longer than normal, it might be a sign that your IUD has moved.

Can I use Lunette with a Contraceptive Ring?

Yes! We’re not trying to prevent you from using your preferred form of birth control. If you are using Lunette together with a contraceptive ring, insert the contraceptive ring before you insert your Lunette Cup. If you’re struggling to take the cup out because the ring is slipping out, don’t panic – it’s a-okay to pop it back in right away.

So does your blood just sit there?

Technically yes, but you don’t have to worry about leakage. Unless you like, absolutely forgot you had the cup inside you because it’s just that comfortable. Your blood might overflow and only then would leakage be a problem.

Sometimes I have leakage when I use the menstrual cup. Can it be related to cervix?

The cervix is the entrance of the uterus through which menstrual blood flows through a pin-sized hole into the vaginal canal. The cervix is cylindrical or cone-shaped and located in the upper part of the vagina. When touched, it feels like the tip of a nose. For some women, it moves significantly lower during menstruation. Since the cervix is usually high in the vagina and the menstrual cup is placed low, the cervix remains above the cup. But if the cervix is significantly low, it may enter the interior of the cup.

Tampons in contrast, are placed further up inside the vagina, where the cervix is located. In Lunette diagrams, the cervix is intentionally placed very high to emphasize that the correct position of the cup is low in the vagina. Leaks are more frequent for women whose cervix moves lower during menstruation or if the cup has been inserted too high in the vagina, next to the cervix, or above it. The cup might also exert pressure on the cervix and cause discomfort and even pain. The best way to evaluate the position of your cervix is by observing leakage — if you have experienced leakage even when the cup has been opened, make sure that the cup is significantly lower than the cervix.

In some users, the cervix fits best inside the menstrual cup. For many users, the cervix descends after giving birth; for others, it is simply situated low in the vagina. If you have given birth recently, or more than once, you should exercise the pelvic diaphragm muscles by doing kegels. Keeping these muscles in shape is useful when using the menstrual cup, as well as to avoid incontinence and improve sex. If you haven’t experienced leakage and you have not located the cervix, there is no need to hunt for it. You’re a woman whose cervix is so deep in the vagina that it does not affect the use of the menstrual cup in any way.

My Lunette menstrual cup has been inside me for ten hours, should I worry?

The usage limit of 12 hours is a recommendation, but longer use will not necessarily cause problems. We recommend changing it 3-4 times a day to avoid any risk of infections.

I managed to get the menstrual cup in, but now I can't get it out! Is the cup stuck inside me?

Relax, you’re not getting anything stuck in there – it’s all in your head! Removing your menstrual cup can be strange at first, so now is the time to practice your yoga breathing and relax. Take a deep breath and focus on your vaginal muscles. If the menstrual cup has worked its way higher inside the vagina, relax the muscles (think happy thoughts) and slowly try to grasp the bottom of the cup with your fingers. Rock it back and forth, and gently ease it out. Squat if you must.

Another strategy would be to find a comfortable position that will allow you to remove the cup more easily. Many Lunette users remove the cup while straddling the toilet bowl with their vagina wide open and legs relaxed (sounds like a pretty view, doesn’t it?)

Methods to reach a cup that is too high

Sometimes users have trouble removing the cup because it is so far inside the vagina and they can't get a hold of the bottom or stem (sometimes the cup moves when you’re sleeping).

In this case, after you wake up, wait at least half an hour to allow it to settle, and then remove. Squatting, in the shower, for example, helps open the vagina and bring Lunette down to the opening. At this point, you can grasp the lower part of the cup with your fingers, sit down in the bathtub (if you prefer), relax, and remove the cup as explained above.

Another removal option is to push downward, using the same muscles as when making a bowel movement (but stop pushing as soon as you have a hold of the bottom of the cup). Relax, remove, and reuse.

My Lunette menstrual cup has started to become discolored over time. Is this normal?

It's normal since blood is quite strong but with good cleaning you can minimize the discoloring.

How often should I get a new cup?

We recommend replacing the Lunette cup every few years depending on how well you take care of it. We have users who have used their Lunette cup for ten years but some prefer to change it yearly.
